6 shows a proposed flow diagram 600 for a media sharing scenario. The AR registers 605 the first application and the second application. The OM receives 610 a trigger from the user for a session setup request on the second application. The OM sends 615 a message to the AR that retrieves the availability and capabilities of the second application. If a second application is available, the OM sends 620 a request for transcoder download to the network. The OM receives 625 a download transcoder module from the network.

Typically, transcoding occurs in a network with individual nodes that perform transcoding. This may not be suitable and / or effective for locally shared media because local video may need to be transcoded in the network. The methods and apparatus disclosed herein perform a transcoding algorithm and download relevant code from a network to a container that is a local entity. Media is transcoded using the downloaded codec. Thus, time and bandwidth are saved. Thus, video / pictures are shared faster among local devices.

7 shows a signal diagram 700 of a media sharing scenario. In this embodiment, the vacation photo is in the first application or device A1 (706). A display, such as a large screen display, may be for the second application or device A2 (707). The applications or devices A1 and A2 may already be registered by the AR, or may be registered 720 at the request of the AR.

A trigger may occur at OM 712 for a trigger for session setup on an application or device A2 (722). The trigger can be a user trigger and can be performed by the application or device A1 with respect to the OM 712. The capability and / or availability of A2 may be confirmed 724 via a message from OM 712 to AR 711, and a capability check may occur 726. The OK message may be sent from the AR 711 to the OM 712. The capability check may be performed 726 between A2 707 and AR 711. An acknowledgment (ACK) may be sent 730 from the OM 712 to the A1 706, and a request for transcoder download may be sent from the OM 712 to the SN 716 with the TA 713. May be sent 732. SN 716 may send a request signal to NSF 717 for transcoder download. The transcoder module may be downloaded 736 from the NSF 717 via the TA 713 by the OM 712. The local IP is obtained and the media path can be set up 738 via the AR 711 from the OM 712 to the A2 707.

Determination of setup completion may be made at A2 707 (740). This may be signaled to the A1 706 by the OM 712. Media, such as photos and / or music 744, and control of media (eg, slide show control) 742 may be received by transcoder 748 from a first application or device A1 706, and may be generated. 2 may be transmitted 746 by transcoder 748 to an application or device A2 707.

For illustration, AR, OM, TA, and A1 may be present in an arbitration device such as a cell phone, and SN and NSF may be present in a network element. Although sharing of photos, such as vacation photos, is shown in the examples disclosed herein, it will be appreciated that all types of media may be shared. Although only two, A1 and A2 are shown for illustrative purposes, multiple applications or devices may be used.
